Up the pressure, you'll know the difference :) you'll need a schrader though if you're using a shock pump.

also, the yellow pages test is normally done from the front, not the side ;p

Ah, but that's cheating - it's easier to for the projectile to spread the pages aside fron an end of the book than it is to penetrate them head on, so it gives the illusion of deeper penetration.

As to your filling arrangement, sounds like a plan :) and word of warning, at high pressure and with such a large C:B ratio, it will be loud...
